[oe] Naming of different recipes for the same package

[Torsten Sadowski]

Hi,

I want to turn my Simpad into a satnav. So I did define a custom image 
including navit. Unluckily, the image is too large. The reason is that speech-
dispatcher uses espeak AND flite with flite being a fat 7MB package. 

I tried to make my own speech-dispatcher package but how can I name it to 
coexist with the default? "speech-dispatcher-noflite_0.6.6.bb" breaks the 
normal ${PN}-${PV} convention and fails during patching:

No file to patch.  Skipping patch.
1 out of 1 hunk ignored
can't find file to patch at input line 52
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff -aurp speech-dispatcher-0.6.5/src.old/tests/Makefile.am speech-
dispatcher-0.6.5/src/tests/Makefile.am
|--- speech-dispatcher-0.6.5/src.old/tests/Makefile.am	2008-01-02 
17:06:47.000000000 -0600
|+++ speech-dispatcher-0.6.5/src/tests/Makefile.am	2008-01-02 
17:13:55.000000000 -0600
--------------------------

Any hints?

Cheers, Torsten
